v IMPROVEMENT IN SCROLL-SAWS.

The Schedule referred to in these Letters Patent and :making part of thesame.

Tov all whom it may. camere- Be it known that I, LOUIS MILLER, ofBaltimore, in the countyof Baltimore and State of Maryland, haveinvented a new and useful Improvement in Scroll-Saws; and I do herebydeclare the following to be a full, clear, and exact description vof thesame, reference being had to the accompanying drawing, in which the gurerepresents a side elevation ot my machine;

This invention relates to that class of scroll-saws wherein 7the saw isoperated by means of a strap passing over pulleys'or rollers andconnecting the two ends of the saw; and

It consists in the combination of the pitman and strap, as shown anddescribed.

In the drawing- A represents the saw-frame,` and B the table upon whichthe work is supported.

C is the saw, and

D is the strap which passes over the rollers or pulleys E F and connectsthe two ends of the saw. 'lhe strap is sufficiently strained to give tothe saw the requisite tension.

G is a crank iiywheel at the end of the driving: shaft, which isactuated by a steam-engine or other power, and to which motion may becommunicated by any usual and wellknown means.

The revolution of the crank-wheel G imparts a rc-V ciprocating motion tothepitman H, and the lower or free end of said pitman is secured to thestrap D at the point d, as shown, by means of screws,pius, or

as above described I 'have found that the saw may beoperated withrapidity and ease, and that the strap becomes a durable and cheap meansof operating the saw with uniform tension.

Having described my invention,

-In combination, the strap D secured to the reciprocating end of thepitman H, to operate as set forthv and described.
